摘要:
Described herein are methods for identifying nucleic acid sequences that modulate the function of a cell, the expression of a gene in a cell, or the biological activity of a target polypeptide in a cell. The methods involve the use of double stranded RNA expression libraries, double stranded RNA molecules, and post-transcriptional gene silencing techniques.
摘要:
The invention features cDNA libraries consisting essentially of cDNA sequences that correspond to different mRNA untranslated region (UTR) sequences separate from adjacent mRNA coding sequences. The invention also features methods for generating these libraries and for identifying a regulatory UTR sequence.
摘要:
Disclosed herein are nucleic acid sequences and their optimized subfragments which are located in the mRNA untranslated regions of therapeutically-relevant genes. These sequences specifically bind RNA binding proteins (RBPs) and/or regulate the mRNA functionality. Also disclosed are methods of optimizing a subfragment of a parent nucleic acid sequence such that the RBP binding activity or mRNA functionality of the parent nucleic acid sequence is preserved in the optimized subfragment.

摘要:
Disclosed are nucleic acid sequences which, when present in an RNA molecule, bind to RNA binding proteins. These nucleic acid sequences are present in untranslated regions of certain mRNA. They can be used in assays to identify compounds that affect the interaction of RNA containing the nucleic acid sequence, such as the source mRNA, and RNA binding proteins. The disclosed nucleic acid sequences can also be used to identify RNA binding proteins that can interact with the sequences. An assay for identifying compounds that affect interaction of RNA containing one of the disclosed nucleic acid sequences and RNA binding proteins is also disclosed. The assay involves detecting interactions between RNA binding proteins and an RNA molecule containing one of the disclosed nucleic acid sequences in the presence of a test compound and in the absence of the test compound. A difference in the detected interaction in the presence and absence of the test compound indicates that the compound affects the interaction. The identified compounds can be used to affect the interaction of RNA binding proteins with mRNA containing the nucleic acid sequences or related sequences.
摘要:
The present invention features compounds useful for inhibiting Rnase P activity. These compounds can be used as therapeutics for treating or preventing a variety of bacterial infections. The compounds belong to several classes including mono- and bis-guanylhydrazones, guanylhydrazone mimetics, and benzothiazolium compounds. Exemplary compounds are compounds of formula (I) Y-(NR')k-U1-(NR'')l-A-(NR1)m-U2-(NR2)n-Z with substituents as described herein.
